Sumana, CAG, commenting on CMDA's notification to widen 422 roads in two of Chennai's Corporation limits, explains that widening roads might seem useful in the short term; but it's simply an invitation for more vehicles. Before long, the CMDA will likely be solving congestion problems again. The CMDA has invited the public to write in with their comments on the proposed changes, before 1st December. Why not write and ask for sustainable roads that prioritise pedestrians, cyclists and public transport over private motor vehicles?
